PACKAGE.

Application filed Kay 31,

To all whom it may concern.

Be it known that we, STANLEY R. HOWARD and GUSTAF W. ANDERSON, citizens of the United States, residing at East Milton, county of Norfolk, and Norfolk. Downs, county of Norfolk, Commonwealth of Massachusetts, respectively, have invented certain new and useful Improvements in Packages, of which the following is a specification.

This invention relates to packages and particularly to a sealed wrapped. package which when so sealed will be perfectly tight but which after the overlying wrapper has been released at its end will free a tongue and expose a delivery opening. It is highly desirable in such packages that the opening operation be made as simple as possible so that ignorance, carelessness 0r haste will not defeat the purpose of providing a neat, convenient and effective delivery.

The tendency in this art has been towards a belief that the end flaps closing such a package must be maintained substantially integral and for this reason various and delivery cartons have been devised in-which the end 'fiaps were left integral or substan-' tially integral, but are adapted to be cut through by a sharp knife so as to form an opening and so as to cut out a flap or tongue to cover such opening. According to our invention we provide a package in which the opening and the flap are ready formed but are so disposed and so held that the flap closely covers the opening in assembly and is held in place by the wrapper which being of thin paper is easily freed by breaking loose or scratching through.

While we do not claim broadly the idea of a carton or container in which a ready formed tongue overlies a ready made opening, we have invented a new and useful form in which the parts are so constructed as to make a strong container for the goods and yet a readily freed and extremely conclosure. Therefore while our invention is capable of adaptation to various styles of package and for a great variety of commodities, we

will only attempt in the present case to show one form. 'This-form is selected as it not only embodies the general principles of our invention but is in itself an extremely 1921. Serial No. 474,030.

useful and commercial form. This form is illustrated in the drawings to which reference is made in the specification by reference characters uniformly applied throughout. In the drawings:

Figure I is a development of the carton blank.

Fig. II an interior View of the carton looking into it with the flaps turned straight Figs. III and IV show the pouring end of the carton before'it is wrapped and perm-anently closed.

Fig. V shows such end after it is permanently closed and prior to final wrapping.

Fig. VI is an end view of the wrapped package.

Fig. VII is a section on the line VII-VII of Fig. VIII and Fig. VIII shows the pouring end ofthe package after it initially opened and reclosed. I

We have shown in Fig. I the blank fro which the carton proper of our novel package is produced. Such blank may be of cardboard, boxboard or other suitable material, and when folded along the indicated lines of fold in Fig; I, produces the bottom closed carton illustrated in the succeeding figures. After the filling of such carton is completed it is-wrapped in an envelopin wrapper W which as appears in Fig. VI seals each seam of the carton so'that the resultant package is dust, air and moisture proof.

The blank consists of a front Wall area 1, a side wall area 2, a rear wall area 3, a side wall area 4:, narrow top end flaps 5 and 6 and bottom end flaps 2 and 4 formed on the side wall areas 2 and 4, respectively, and wide top end flaps 7 and 8 and bottom end flaps 1 and 3 formed on the front and rear wall areas 1 and 3. The rear wall area 3 has a relatively narrow laterally disposed closing flap 9 and provided at its ends with tongues 10.

When the. carton is folded the flap 9 is glued under the side 4 as shown in Fig. VII, its end flaps 1O lying against the top and bottom flaps. The bottom flaps l and 3 and 2 and 4 are folded under and glued in the usual manner in a bottoming machine. The package is then filled and the top flaps 5 and 6 first turned in and glued and the has been flap 7 laid thereon so as to be permanently attached. The flap 8 is then bent down over the flap 7 and held in place by an adhesive strip 11 drawn over the top of the package. The package is then passed to the wrapping machine and the wrapper W applied thereto preferably as a completely sealed wrapper.

The end flaps of the wrapper are preferably printed with a cutting line P so disposed as to exactly overlie the edges of the flap 8 so that a knife passed along the line P will sever the wrapper N and the strip 11 and completely free the flap 8 which is unglued so that it can be raised to expose the opening 12 in the carton and flap 7 thus making the contents of the package readily available for use. \Vhen it is desired to temporarily seal the package after it has been initially opened, the tip 8 of the flap 8 is bent on the dotted line 8 shown in Fig. I and in the manner indicated in Fig. VII and is thrust down adjacent the short side 12 of the opening 12.

The flaps 5 and 6 are slitted as at 5 and 6 just far enough .to receive the full width of the folded tip 8 when it is thrust into position as shown in-Fig. VII. Fig. VIII shows an end view of the package with the tip folded in this same position.

It will be seen that the flaps 5 and 6 support the flap 7 and extend slightly beyond the inclined edges of the opening 12 so as to support the flap 8 when it is tucked in in the position shown in Figs. VII and VIII. In order to receive the tip 8 therefore, the flaps 5 and 6 are slitted as at 5 and 6 to a sufiicient width to permit the breadth of the flap 8 at the line of its bend as iridicated at 8 to pass through and be completely seated as indicated in Fig. VII. When so seated the flap 8 makes asatisfactory and convenient temporary seal for the opening which results from the superimposing of the flaps 7 over the flaps 5 and 6. This opening as shown in Fig. IV is slightly reduced in area from the complete opening 12 of the flap 7 by reason of the encroachment of the flaps 5 and 6 which extend slightly beyond the lateral sides 12 and 12 of the opening 12.

\Vhen completely sealed our package end as indicated in Fig. VI is completely covered by its wrapper, which in the disposition of its flaps is the same as the opposite or permanently sealed end of the package. The only difference is that the wrapper is so printed or marked by the lines P with suitable instructions as to opening that the true edge of the flap 8 is indicated so that a knife out can be made to cut the outer wrapper IV and the sealing strip 11 and thus free the flap 8 for opening.

Our invention is capable of use in a variety of cartons and in a variety of packages whether wrapped or unwrapped and is therefore capable of various modifications in the details of construction of parts, all with-. out departing from the spirit of the invention if within the limits of the appended claims.

What we therefore claim and desire to secure by Letters Patent is:

1. In a container, a carton member including end closure flaps, one of said flaps having a cut out portion, lateral flaps hav ing their ends underlying said out out portion, and slitted laterally, and an overlapping fiap adapted to. cover said out out portion and having its tip adapted to be bent to enter'said cut out portion and said slits to close the same after initial opening. a

2. In a sealed wrapped container, a delivery end structure comprising superimposed flaps including an outer unglued flap and glued inner flaps, one of said inner flaps having a delivery aperture therethrough and two lateral flaps having their ends contoured to extend partly within said opening and laterally slit to receive the sides of the bent tip of the unglued flap when reclose after initial opening.

3. In a sealed wrapped container, a delivery end st-ructure comprising superimposed fiaps including an outer flap and inner flaps, one of said inner flaps having a delivery aperture therethrough and two. lateral flaps having their ends contoured to extend partly within said opening and later ally slitto receive the sides of the bent tip of the outer flap when reclosed after initial opening.

4. In a sealed wrapped container, a delivery end structure comprising superimposed flaps including an outer flap and inner flaps, oneof said inner flaps having a. delivery aperture therethrough and two lateral flaps having their ends contoured to conform to said opening and receive the bent tip of the outer flap when reclosed after a initial opening.

5. In a container having a plurality of foldable end flaps including a flap on one side of substantially the size of the container end and having an aperture, short flaps in the two adjacent sides and disposed beneath the apertured flap and each having its end extended and underlying the margins of said aperture, and a taperedfiap on the fourth side substantially the length of the apertured flap and shaped to fit the aperture of said first named flap, but having its tip extended beyond said aperture to overlie its margin in position of permanent seal, but adapted to be folded down at the edge of the aperture to be tucked into said aperture for temporary closure.

6. In a container having a plurality of 'foldable end flaps including a flap on one side of substantially the size of the container end and having a trapezium like aperture, short flaps on the two adjacent sides and disposed beneath the apertured flap and each having its end extended and underlying the margins of said aperture, and a tapered flap on the fourth side substantially the length of the apertured flap and shaped to fit the aperture of said first named flap, but having its tip extended beyond said aperture to overlie its margin in position of permanent seal, but adapted to be folded down at the edge of the aperture to be tucked into said aperture for temporary closure, the edges of said side flaps underlying said aperture being slitted to receive the tip of said tapered flap when folded and tucked in.

7. In a container, a carton member including end closure flaps, one of said flaps having a cut out portion, lateral flaps having their ends extended within said out out portion, and an overlapping, free flap adapted to cover said out out portion except for narrow spaces along its sides, a holding strip across said tongue and crossing said spaces,

8. In a container, a carton member including end closure flaps, one of said fiapsha'ving a cut out portion,'lateral flaps having their ends extended Within said out out portion, and an overlapping free flap adapted to cover said out out portion except for narrow spaces along its sides, a holding strip across said tongue and crossing said spaces, and having its tip adapted to be bent to enter into said out out portion to close the same after initial opening.

In testimony whereof we affix our signatures in presence of two witnesses.
